Best Laser for a Hypertropic Scar with Discoloration?

Greetings: I have a surgical scar. There also is some darker discoloration. I have become so confused though, with all the different lasers. Which do you recommend would be best to help? The scar is itchy and easily irritated, in an area that gets a lot of movement so it also aches at night. It is now one month old.
